I'm wondering if there's a word that describes this type of language sneakiness:
I asked my boyfriend to stop talking to his ex-girlfriend, or I would break up with him. He agreed to stop talking to her. A week later, I find out he's been texting her all along, and when I confronted him, he said, "I said I'd stop talking to her, I didn't say I wouldn't text her."
This is just a made-up story, but I am wondering if there is a word in English that describes precisely this kind of deception.
Kind of like using semantics to get over on someone. Like a bad (or good?) lawyer, I guess.
Anyone have any ideas?
